If you use skating for your primary cardio workout, or you like to skate just for fun, then the K2 F.I.T 84 Boa is the ideal skate for you. Technically, it repeats itself from last year, but in a fun new color scheme. The big difference between this guy and it's brother the F.I.T. 84 is the addition of the Boa Speedlacing system...which we here at Londo Mondo love! We will all attest to the amazing comfort, quickness, precision, and longevity of this system. V02 Alu frame, 84mm wheels and ILQ-7 bearings come standard. This skate has most of the capabilities of the Mach 90 and all the comfort. You can roll a half marathon on these bad boys and come out smiling. You won't have the fastest time, but they will hold up just fine.
